As a developer, understanding how to deploy full-stack applications in the cloud is a critical skill. In this guide, I demonstrate how to build and deploy a 3-tier web application using React, Flask, and PostgreSQL, hosted entirely on AWS.
This project covers:
- Frontend: React application for user interaction
- Backend: Flask REST API to handle database operations
- Database: PostgreSQL hosted on AWS RDS
- Hosting: AWS S3 for static frontend and Elastic Beanstalk for backend
What You’ll Learn:
- Setting up PostgreSQL locally and on AWS RDS
- Running Flask backend locally and creating APIs (/add, /list, /delete)
- Running React frontend locally and connecting it with Flask
- Deploying Flask backend on Elastic Beanstalk
- Deploying React frontend on S3 static website
- Configuring AWS security groups, permissions, and IMDS
- Connecting frontend and backend in the cloud to make a fully functional web application
This tutorial is hands-on and developer-focused, giving you practical experience from local development to cloud deployment.
